Marine organisms normally swim at elevated speeds relative to cruising speeds only during strenuous activity, such as predation or escape. We measured swimming speeds of 29 ram ventilating sharks from 10 species and of three Atlantic bluefin tunas immediately after exhaustive exercise (fighting a capture by hook-and-line), and unexpectedly found all individuals exhibited a uniform mechanical response, with swimming speed initially 2 times higher than the cruising speeds reached approximately 6 hours later. We hypothesised...
